Preventing Breast Cancer ...  1996 
This book uncovers  the major cause  of 
the recent breast-cancer  incidence  in the 
USA.  The author  shows that past exposure 
to ionizing radiation ---  primarily medical 
X-rays  —-~  1s responsible for about 75 
percent of the breast-cancer problem in the 
United States. 
The good news:  Since the radiation 
dosage given today by medical procedures 
can be significantly reduced without 
interfering with a single useful procedure, 
numerous  future cases  of breast-cancer can 
be PREVENTED. 
The author recommends  specific actions 
to start breast-cancer prevention now,  not 
ten years from now.
Thanks to the talents and generous  effort of David T. Ratcliffe,  a 
growing number of this book’s chapters (and various other works of the 
author) are available on the Internet at:

The HEIR-2 Report (1996) 
The Committee  for Nuclear Responsibility,  Inc. (CNR) is a non-profit 
educational  group organized in 1971  to provide independent analyses of the 
health effects and sources  of ionizing radiation.  Authors of CNR 
publications speak for themselves alone and not for CNR’s entire Board, 
whose members are known for their own independent thinking. 
This study, PREVENTING  BREAST CANCER,  is the second one in 
CNR’s series of reports,  "Health Effects of Ionizing Radiation"  (HEIR 
Reports). 
The previous report (1990) was RADIATION-INDUCED  CANCER 
FROM  LOW-DOSE  EXPOSURE:  AN INDEPENDENT  ANALYSIS,  also 
by Gofman.  (See, for example,  reviews in Choice, J anuary  1991; in the 
New England Journal of Medicine,  February  14, 1991; in the Bulletin of 
the Atomic Scientists, January  1992; in the PSR Quarterly,  March  1993.) 
The third HEIR Report will be a study, covering both males and females, 
of the causal role of medical radiation in the overall cancer problem ---  not 
in breast-cancer  alone. 
Research in this field is not commercially viable.  Most radiation research, 
analysis, and publications are sponsored by government grants.  CNR 
neither requests nor would accept any government funding.  The low price 
of the HEIR Reports is made possible by the foundations  and individuals 
who generously support these scholarly works, and by the refusal of the 
author to accept royalties or payment of any other sort from CNR.

Preface and Acknowledgments 
Writing this book has been a happy task. It deals with a 
very serious problem, with a very happy ending. It would be hard to 
think of anything more rewarding for this effort than the knowledge that 
we can begin the task of breast-cancer prevention ---  now. 
People have often asked me to write a book which has no numbers, 
no mathematics,  no symbols, no equations.  I appreciate their fear that they 
will not understand.  We, who have worked on the preparation of this book, 
think that anyone can understand the fascinating past history of 100 years of 
the x-ray in the production of breast-cancer. 
Simply accept "numbers"  the first time through.  The story will tell 
itself that way. And then come back, if you are so inclined, to challenge all 
the numbers.  The numbers are your insurance that this story has real legs. 
Three people have made exceedingly large contributions  to the book. 
Many improvements in the writing come  from them.  Professor Helen 
Gofman patiently brought the perspective of a pediatrician and a general 
physician as she meticulously went through the manuscript to tell me where 
it would not be understood without changes. 
Egan O’Connor,  our Editor of CNR Books, not only put a rough 
manuscript into the English language, but provided a clear, cool, critical 
head in challenging everything placed before her. 
John David Gofman, M.D., my son, volunteered to "look the 
manuscript over," and indeed he did.  All the pages,  and all the lines. 
His insights, his advice, his knowledge made a very large difference in 
the final book which evolved through his and Egan’s critical comments  and 
contributions  to ideas and style. 
Lastly, there is one special place in my heart, for an assist which 
'  was absolutely essential.  That place is occupied by the superb library of 
our medical school at the University of California in San Francisco.  What a 
treasure —--  a collection so rich as to make the trip back through 100 years 
of medicine an easy one.  And the cooperation of the librarians was  superb. 
This is the beginning of an effort to prevent cancer in one effective 
manner.  Most of the methodology will be applicable for an effort with 
cancers  other than those of the breast.  Indeed, we hope other investigators 
will make their own  studies using such methods as are presented.  For the 
inevitable errors  and unclear passages,  I take all the credit.  We shall try to 
improve later editions as we learn of such flaws.

Another book (the HEIR-3  Report) is in preparation by this author, for 
publication probably in 1996 or maybe early 1997.  The HEIR-3  Report 
explores the hypothesis that earlier medical  irradiation has caused not only 
most cases of breast-cancer,  but also a large share of the cases  of other 
cancers,  in both men and women.  The ISBN is 0-932682-97-9,  from 
the Committee  for Nuclear Responsibility Books.
